Gadget Infinity Battery Grip?

[RyanLilly]

I was just looking at the Gadget Infinity Vertical battery grips for my 20D. Has anyone used them? It supposed to be an exact clone of the canon model, and looks just like it from the photos. Everyone seems to be generally happy with their flash triggers, so I think I may give it a shot. I've looked at the other off brands, but the canon or gadget infinity clone looks the most comfortable. I'd love to here from anyone that has used them.

Thanks,
Ryan
